Our MV reactors are dry type iron core three phases or single phase, made by H class copper wires. Reactors have the features of high linearity, high over-load capability and low losses. All the materials can be recycled and environment-protective. Vacuum impregnation by special resin material provides better insulation function, high voltage stress, low noise and long lifetime, as well as water-repellent. The number and position of air gaps are selected in order to minimize losses in magnetic core and windings. Limbs, yokes and air gaps are blocked by adhesives and pressing elements designed to reduce acoustic noise. The reactors are designed with natural air cooling. All products are passed by TUV EN 60076-6 certification.
